To all whom if may concern Be it lrnoivn that l, @nanars lil?. Youn/s, a citizen ot the llnited States, residinga at inalia, inthe count-y ot Douglas and State ot Nebraska, have invented certain new and useful lmprovements in lTloor Construction, of which the following is a specitication.

.This invention relates to an in'iproveinent in floor construction providin@1 a tire-prooii layer or liller between a concrete tloor-tiase and the Wood flooring.

'ilhe invention is illustrated and described in connection with a reinforced, concrete door base employed to prevent hre troni communicating trom one story of a build ing to another, and Where Wood, supported by the concrete base is used as a material tor the flooring. `Wo0d binders tloonsereeds are generally employed between the tloorboards and hase tor holding the nails, and to operate as spacing members, so that the tloor when laid, will present a smooth or'dat surface. lt is desirable in the construction ot tloors oit this class, that screeds be provided which vvill hold the floor nails, and

will not beinjured by lire, also that they be so constructed that they will not co1nmunicate re trom one part of the tloor to another, and will not rot cr decay trom action ofthe acid contained in the concrete, and that they be so arranged that they will not be moved in any direction to permit vibration ot the tloor boards or strips. Also it is desirable that a contact be prevented ot the wood floor with the concrete losse, and that all parts ot the base, adjacent to the floor strips or boards, be covered, to prevent decay ot the Wood; and to prevent decay, it .is an advantage to provide an air space below the ivood floor. f

lhe invention includes a floor construction wherein a binder or screed is employed which may be conveniently molded as linished article betere being laid, ot lireproot material, will he nontragile and"adapted to l hold l the nails ot the itlooring, and ot' such construction that it will adhere to the mortal" which embraces its sides and bottom, and will not cause rot or decay ot the Wood Flooring With which it makes contact 5.also to the provision of grooved plates tor covering' the greater part ot the cement or concrete base, in the channels between the i screeds, and which may be conveniently molded of lire-"prooi",n material, and adapted to be disposed end-to-end with their grooves!

in register to provide conduits or air-pacsag'eivays extending the entire Ywidth or length oit the concrete base.

By use oit the construction to be described, the tloor may have a lighter weight than ordinary, anda considerable saving; of time is etlected in completing the tloor since the movement ot air through the grooves of the plates conveys all moisture trom the base, and the parte employed are practically de void ot moisture, ettcept the plastic mortar, of which, however, only a limited amount is used.

Referring.r now to the elmo/iop,r tor a more particular description, numeral l indicates a cement or concrete iloor-base, having any desired thickness or area; and to provide a suitable ller between the base and wood .door-boards or strips 2, which will be lireproot and will be adapted to conduct nioisv ture trom the base, and will not become injured or decayed `trom action ot the acid con.

tained in said base, the construction now to be described is employed.,

'lo construct the herein described filler, a plurality ot :tloonscreeds 3 are disposed substantiallyparallel upon adhesive layers 4t, said layers consistini?,` ot .mortar made, preterably, ol one part igypsum cement plaster and one partsand, mired with Water so that the plastic mass will adhere to the concrete base and to lthe surface ot' the tloor-screcds- The tloor-screeds, best shown in Fig. 2,

- ing or sand and of thicknes may have any desired length, and each consists of a wood core a: upon which, hemp or jute b is loosely wound, or light wire may be used as a wrapper therefor, and a coating c is then applied, consisting ot gypsum or gypsite heavily mixed with sisal jute, sisal hemp or other line, flexible, heavy binder, the screeds being preferably formed in molds so that they will be substantially rectangular in cross-section and of substa-ntially uniform width and thickness, The wood cores operate as holders for the nails a: which are used when the lloor is secured to the screeds, the adhesive element l operating to connect the screed with the base and to hold them in rigid relation. llhile the nails penetrate the coating, they will not cause tract-ure or breakage thereof. The screeds are disposed on the beds while the latter ar l that their upper suriaces wil Zontal plane to pieviv c contact with the! door boards; and on account ot the construction or the screeds described, they operate to prevent th" destructive acids contained in the base to the wood boards or strip porous layer G is then base between the screet ereiaoly equal to that or' the mortar el. it 7 are indicated rectanguiar plates, each being 'formed on one of its sides with substantially parallel grooves d. These plates may be molded, and any nonconducting or fire-proof material of light weight may be used in their construction, such as gypsum, plaster of ?aris, or gypsite; also Fort-land cement with a limited percentage ot saw dust may be used for molding these plates. rlhe grooved plates 7 have a thickness less than that ot the screeds and are disposed adjacent to and between the screeds to form air spaces or chambers 8 between the plates and licor strips 2, and to form recesses 9 at the sides of the screeds. fter these parts have been arranged as described, and before the wood ldoor strips have been secured to the screeds by nails mortar l0 in plastic form is deposited in recesses 9, and as the parts with which it comes in contact are practically devoid of moisture, said mortar will readily become dry and hard; also, this mortar being of the same constituent parts as that of layers d, it will adhere to the base, plates 7 and to the screeds; and plates Z will be securely held in their positions as shown in the drawing.

As thus described, a liller is provided between the wood parts of the floor and the base, which will adequately support the Hoor strips and protect it from a contact with the base. It will be understood that the coatings of the screeds protect their cores from action of the acids contained in accesso the concrete base, and that the adhesive members l and l0, cause the screeds to cling, respectively, to said base and to the grooved blocks 7, and these are important features, since vibration of the floor strips will be prevented, and the construction will be durable.

lt will be seen that it the wood floors are injured or destroyed by tire, the screeds may remain uninjured, and will not cause tire to be communicated in chambers 8 trom one part of the floor to another. The grooves (Z of plates Y which communicate with each other when said plates are disposed end-toend, provide conduit-s for the ventilation oit damp air emanating from the concrete base, by use of the herein described iiller, the tlc-ors of buildingsmay be laid without waiting ior evaporation.

"in ord e movement in the conduits formed by groove o3 purposes or" ventilation, te ninal grooved putes Y may be employed, these bein-g in all respects the same those already descri d, except that they at their ends with recesses i is shown in g. 6, plates l" may be used adjacent to the wall ll ot' a building, the air `from said conduits move upwardly through suitable grooves y termed in the base-boards l2, adjacent to the wall of a building. y
